MACHIENE FOR. SET'EIDl'C-Z- BLIND Application filed April 20, rare, Serial No. 833,071.

To all wiwm it may concern.

Be it known that l, Josnrrr W. BARNA a citizen of the United States, residing at Chicago, in the county of Cool; and State of llllinois have invented certain new and useful Improvements in Machines for Setting Blind Eyelets, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to machines for setting eyelets or other fastening devices in sheet material and more particularly to machinesfor setting blindor invisible eyelets in the uppers of boots and shoes.

in setting invisible the outer part of the upper is perforated and the eyelets are set in the lining or stay in register with the holes in the outer part of the upper. lin setting blind eyelets the operation is reversed and the eyelets are set in the outer part of the upper in register with holes punched through the lining or stay. An object of the present invention is to provide a machine by which the operations incident to setting either blind or invisible eyelets may be carried out with im proved accuracy and certainty.

An important feature of the invention consists in the combination with a tubular punch for perforating one of two superposed layers of material, of a punch and die for perforating the other layer, and devices forsetting an eyelet in the hole thus formed in one layer. A machine organized in this,

manner may be utilized to punch holes in the two layers of material of the diameters best suited to the characteristics of each piece. For example, a relatively small hole may be punched in the part in which the eyelet is to be inserted and under these circumstances the holding of the eyelet is improved. The punch and die may also be utilized advantageously in perforatlng the textile material which is often found in one part or the other of a shoe upper.

As herein shown an anvil 1s provided which serves the combined functions of a cutting block for the tubular punch, a

punching die for the solid punch and an upsetting die for clenching the eyelet. lit isbelieved that aidevice of this character has not been used heretofore in eyeleting machines. llts advantages in point of sim- Specification of Letters Patent.

The machine frame comprises a base from which project a pair of standards and 26 connected at their upper ends by a horizontal portion 27. A'second pair of standards 21 projecting from the base are provided with bearings for the main shaft 22 which is driven from a pulley through a operator through to the connecting a tracl: or guide comprises a vera treadle rod 24. Secured portion '27 of the frame is 28 for the raceway which tically disposed flange or bar 29 and raceway track 32. The raceway is provided at its upper end with a reservoir (not shown) the lever against the periphery of the cam and consequently to move the raceway rearwardly into inoperative position at the proper'time.

The connecting portion 27 of the frame is provided with vertical bearings for a plunger 39 which carries at its upper end the solid punch 48 and the eyelet inserting die 43. The plunger 39 is connected at its lower end to an arm 40 pivoted at 36 to the machine frame and connected between its ends to a cam follower 41. The arm 40 is oscillated through the follower 41 by a cam 42 on the main shaft 22, see Fig. 1.

The plunger 39 is provided in its upper end with a bore in which is received'the shank of the lower or eyelet carrying set'43. The set 43 has a centrally disposed passa e for the punch 48 which also acts-as a spindle to take an eyelet from the raceway and hold it in position upon the set. The upper end of the set is provided with a concave surface 50 to fit the flange of the eyelet. The body of the set 43 is shouldered and rests upon the upper end of the plunger 39 being retained in place by a set screw 45. A compression spring 46 is arranged in the bore of the'set 43 beneath the punch and acts normally to holdthe punch in itsv uppermost position.

Within the spring 46 is a post or 'stop 47 which is arranged to engage the end of the punch 48 positively after the latter has been depressed for a predetermined distance.

The spring 46 is strong enough normally to force the punch through the work but yields to allow the set to rise along the punch to insert theeyelet when the.u ward movement of the punch is arrested y the anvil.

However, in case the spring is not sufliciently stifi to force the punch through the work the post 47 will positively advance the punch to efl'ect the punching operation. The distance between the top of the post 47 and the lower end of the punchis substantially equal to the length of the eyelet barrel.

The punch 48 is reduced in diameter at its upper end thus providing a shoulder 49 adapted to engage with the underside of the anvil through which its upper reduced end may freely pass. The diameter of the unch 48 above the surface 50 of the set is su stans tially equal to the interior diameter of the eyelet barrel so that the latter will be accurately held in place during its insertion.

53 which acts as a punching die ing to punch the hole in the lining art 3 of the upper in which the eyelet is to e set.

On the lower face of the anvil there is formed an upsetting surface 55 which is disposed concentrically with respect to the passage 53 through the anvil. The inner annular edge 54 of the upsetting surface constitutes a shearing ed e which cooperates with the punch 48 as will be apparent from Fig. 7.

The upper face of the anvil about the openin of the passage 53 acts as a. cutting block or a tubular punch 57 which is arranged for movement above the anvil in the forward end of a lever 61. The punch 57 is provided with a lower cutting edge 58 adapted to be forced through the outer or leather part w-of the upper in punching the lacin passage. The interior diameter of the punc 57 is substantially the same or slightly larger than the diameter, of the passage 53 in the anvil. The arrangement is such that the they are discharged at its upper end through 0 an opening 59 in a hollow adjustin screw 60. The tubular punch 57 is ad ustabIy mounted in the free end of the .levcr 61 pivoted upon a stud 62 to the machine frame and being secured at its rear end by a stud 63 to the upper arm 64 of a cam follower 65 which surrounds a cam 66 on the shaft 22. The tubular punch 57, the anvil passage 53 and the solid punch 48 are all brought into alinement in the operating movement of the two punches so that in a single continuous operation the lining part 3 of the upper will unchings formed I be punched, an eyelet will,be set in a hole 1 thus formed in the linin and a lacing passage hole will be punche in the outer part a: of the upper above and in alinement with the eyelet.

The work is 'fed after each eyeleting operare set but a short distance from the margin of the quarter. The jaws 67 and 68 are carried upon the free ends of a pair of crossed arms 69 pivotally mounted at 70 upon the upper end of a laterally oscillating carrier member 71 which in turn is pivoted to the base 20 upon a pin'72. The carrier member 71 is therefore adapted to be moved laterally in a direction to advance the work across the anvil. The free end of each arm 69 is pivoted to one end of one of a pair of links 73 and the free ends of these links are pivoted at 74 to the upper end of a spring arm 75 secured by bolts 76 to a rockin lever 77. The lever 77 is pivoted at 78 to Ere oscillating carrier 71 so that it partakes of the lateral movement of the latter. The upper end of the arm 75 is swung forwardly into position to open the jaws by a torsion spring 79 which encircles the pivot 78 and is connected to the arm and to the oscillating carrier 71. The arm 75 is drawn rearwardly when the lever 77 is moved forwardly by the action of a cam 80 on the shaft 22 which is arranged to wipe against the roller 81 mounted in a rearwardly extending portion of the lever 77. lit will thus be seen that the jaws 67 and 68 are closed upon the work when the arm 75 is drawn rearwardly and when the cam 80 passes 0d the roller 81 the spring 79 immediately moves the arm 75 forwardly into the position shown in Fig. l to open the jaws. The cam 80 is timed to permit the edges to be closed after each punching inserting operation and to hold them closed during the feedin of the work which is effected by the osciTlation of the pivoted carrier.71. The carrier 71 is normally held against the machine frame and with the feeding jaws adjacent to the anvil by a spring 82 which acts upon a projection 71' indicated near the base of the carrier. The carrier" is guided in its movement by a pair of laterally extending flanges 83 which are secured to the frame.

The carrier 71 is given its feeding movement by a reciprocating wedge member 84 which is mounted between the frame and the member 71 upon a swinging arm 85. The arm 85 is pivotally mounted upon the base 20 and held against the cam 86 on the shaft 22 by a spring 87. At each revolution of the cam 86 the wedge is forced forwardly and acts to swing the carrier member 71 outwardly so that the feeding jaws are carried away from the anvil. This movement of the carrier 71 is timed to take place while the jaws 67 and 68 are closed upon the work as already explained. The wedge 84; is moved reversely to permit the jaws to be returned to initial position while the jaws I are held open and while the work remains 'at rest.

In order to regulate the extent of the an adjustable arm 88, see Figs. 12 and 13 which is pivoted on a pin 89 to the upper end oftlie actuatingarm 85. By swinging the arm 88 up and down toward the pivot of the carrier 71 the throw of the carrier may be varied. The arm 88 is arranged to be held in adjusted position by a pin 90 which passes through an elongated slot 91 in the arm and into a series of spaced holes 92 on the frame 26. Tn order to insure a uniform action of the wedge on the carrier 71 in all adjusted positions of the former the carrier 71 isprovided with a rearwardly extending plate 93 having its edge arranged in the path of the wedge and on a curve and the center of which is the point of contact of the arm 85 and the cam 86. In order to make the carrier 71 more quickly responsive to a short movement of the arm 84 the arm is provided upon its under face with a bevel 94c widening downwardly so that the effect of the movement of the arm is increased when the arm has moved toward the pivot of the carrier 71 and vice versa. The roller 81 is elongated sufficiently to be engaged by the cam'80 in all lateral positions of the carrier 71.

A presser footor stock clamp 95 is arranged to be reciprocated in the horizontal portion 27 of the frame in line with the under side of the anvil 51 in order to clamp the lowermost part of the work against the anvil while the feeding jaws are moving reversely. At its lower end the stock clamp is pivoted to the end of a curved link 96 which in turn is pivoted at its rear end upon a stud 97 in the standard 25. The link 96 is oscillated in one direction by a cam 99 on the shaft 22 and in the other direction by a spring 98. It will be apparent from Fig.

2 that the spring 98 acts to elevate the link 96 and so move the clamp 95 into operative position and the cam 99 positively depresses the clamp. A treadle rod 101 is connected to the link and affords means by which the operator may depress the clamp away from the upper in presenting the work.

11 edge gage 102 is adjustably mounted in the upper end of the clamp 95 and extends rearwardly toward the raceway where it is provided with an upwardly extending projection. This projection forms a gage against which the edge of the material may be held in order to determine the distance of the eyelet line from the edge of the work.

In operation the work is presented to the machine with the part in which the eyelets are to be set beneath the anvil 51 and with the point at which the first eyelet is to be set in alinement with the punches 48 and 57. The machine is then set in operation whereupon t-heraceway is at once advanced toward delivering position and the plunger 39 is elevated to carry the punch 48 into the endmost eyelet of the raceway. The raceway is then retracted leaving the eyelet to seat itself upon the set 48 and in the continued upward movement of the plunger 39 the punch 48 is forced into the punching die passage 53 of the anvil thus perforating the lower layer of the work. Meanwhile the tubular punch 57 is forced downwardly against the upper surface of the anvil and the upper layer of the work is perforated. The plunger 39 continues to move upwardly advancing the punch 48 through the passage 53 and thus forcing the punchings into the bore of the tubular punch 57 When the shoulder 49 of the punch 48 encounters the openingof the passage 53, thepunch is arrested and the set 4.3-continues to advance inserting the eyelet barrel through the part 3 of the work and clenching its barrel against the upsetting surface 55 of the anvil. The punches are then retracted and the feeding operation immediately takes place after which the parts are returned to initial position in readiness to begin a new cycle of operations.

The operation of the machine has been described in connection with setting blind or invisible eyelets but it will be understood that many features of the invention may be utilized to good advantage in fastener setting machines of general application.
